"She was a fair girl, with bright blue eyes and short wavy flaxen hair, very soft to the eye. Lady Glencora was short in stature, and her happy round face lacked, perhaps, the highest grace of female beauty. But there was ever a smile upon it which it was very pleasant to look at; and the intense interest with which she would dance, and talk, and follow up every amusement that was offered her, was very charming" - The Small House at Allington
